Corneilus Ferguson was my grandfather (b. 1893; d 1972). He came to WA from Missouri and worked in the lumber industry before marrying my grandmother (Calla Sines). In later years they moved their family to sourthern Oregon/N.CA to farm and homestead land at Tulelake. His mother was Margaret Elizabeth. Somehow there are Yokums in this family too. He has several brothers and sisters. Clarence, Charles, and Ruby are a few of the many siblings. I am looking for a family line here. Siblings of grandpa's, parents and further back. Any help is appreciated. Thanks.
